British Warplanes of World War II by Danuel J. March (1998, Aerospace Publishing) gives 4411 built by Airspeed itself at its Portsmouth factory (which is the only production figure I can spot in the article) 550 at Christchurch, 1515 by de Havilland at Hatfield, 1360 by Perceval at Luton and 750 by Standard Motors at Coventry, giving a total of 8586.Nigel Ish (talk) 10:25, 13 November 2011 (UTC)

These figures are confirmed in an article in the June 1980 issue of Aeroplane Monthly magazine.Nigel Ish (talk) 10:33, 13 November 2011 (UTC)

The Oxford is quoted with both the type/model number AS.10 and AS.40, anybody know at what point they changed. Most of the sources use AS.10 or AS.40 sometimes for the same aircraft ! but with no explanation. MilborneOne 20:42, 4 March 2007 (UTC)
